Adolescent Fertility Rate

What does it mean ?

This indicator represents the number of babies born to girls and women aged 15-19 each year. It can be understood as the expected number of girls that will become pregnant between the ages of 15-19 each year out of 1,000 girls in that age group.

Why does it matter ?

In countries where child marriage is common, it is also likely that a high adolescent fertility rate will result. The marriage of girls followed by multiple childbearing either in early or late teen years is a violation of human and reproductive rights, as well as a missed opportunity to improve levels of female literacy, education and the economic progress that is associated with female participation in the labour force.

How is it collected ?

A national survey was undertaken in each country from a representative sample of households where women and girls were asked how many children they have given birth to and when they occurred. Using data from girls aged 15-19, a fertility rate was calculated by adding the number of births within the year before the survey, and dividing by the number of girls in the survey aged 15-19.

Alternative Data Sources

The data for each indicator on African Health Stats (AHS) are published by the UN agency, or UN inter-agency group, which holds responsibility for global monitoring of the indicator. This varies by indicator. Please refer to ‘Data Source’. AHS uses data from these sources because such data are internationally comparable and it is the mandate of those agencies to prepare such data and monitor progress internationally. In some cases the UN agency has made adjustments to the data in order to make national data internationally comparable, for example they may adjust national estimates to account for differences in survey design, the extent of potential underreporting, and the definition of what is being measured (eg. maternal deaths). This means that at times there may be discrepancies between national and international estimates. Individual countries may prefer to instead rely on national figures for national monitoring. For uniformity, AHS uses only international estimates of the UN agencies in data visualisations.

A national survey was undertaken in each country from a representative sample of households during which women and girls were asked how many children they have given birth to and when the births occurred. Using data only from girls aged 15-19, a fertility rate was calculated by adding the number of births within the year before the survey, and dividing by the number of girls in the survey in the same age range.
